An art platform combined with a blockchain allows you to store a finite number of outputs from the same system definitively without knowing upfront what the outputs would look like. This forces you to think carefully about your system: it should produce interesting works with each iteration. Some people call this long form generative art.

Yah, I think the question really comes down to: what's so special about a block chain vs any other public record or database?
For example, it's just as easy - and more accessible - to put the code and example configurations with output in a github repository.
